Amazon Warehouse Deals offers the used Western Digital 2TB Elements USB 2.0 External Hard Drive, model no. WDBAAU0020HBK-NESN, for $70.81 with free shipping. That's $0.04/GB and $11 under the lowest total price we could now find for a new unit, although we saw it new for a buck less in July. This drive uses GreenPower technology to reduce power consumption by up to 30%; it runs at 7200 rpm.
